1)Terms
and conditions

a)If
a change or modification to the stock engine or its parts is not included in
these rules then the modification is considered legal.

a)No
limited production race motors allowed. Must be a production motorcycle
engine, 4 cylinders, 4 stroke

b)No
titanium anywhere in or on the engine, unless it comes stock form
manufacturer of engine on the production bike or used as bolts in
aftermarket rods.

c)Must
have engine, clutch, and transmission all in one unit

d)Must
be Chain Drive

3)Bore
and stroke

a)600cc
Maximum displacement for an engine model that was new in 2006 or newer.
Older engines maximum displacement is 637cc. Engine model is defined as a
manufacturer redesign of overall engine. See Specification list.

ii)Valve
seat inserts may be reworked or replaced with any seat of original
dimensions.Any dimensional
thickness of the stock inserts may not be increased.Valve seats can be ground with multiple angles.Blending of the valve seat into the head is permitted but cannot
extend more than ¼” into the aluminum head measured from where the seat
meets the head.

b)OEM
Head only.

c)Cam
may not have a higher lift than the stock factory cam. (duration is open)

d)Valves
cannot be larger in diameter than factory stock valves.

5)Bottom
End

a)No
machining to remove weight from the crank (balancing of crank is ok) (no
after-market cranks) (no lightweight cranks) No polishing or coatings of any
kind

b)No
aluminum connecting rods.

c)No
dry sump systems are allowed unless it comes from the motorcycle
manufacturer as original equipment.

6)Clutch/Transmission

a)No
removal of clutch.

b)Clutch

nonstandard gear-ratios. All gears must remain in transmission, no removing

7)Ignition

a)No
aftermarket ECU’s, stock appearing ECU only. ECU must be a production ECU
that was originally supplied by the same manufacturer as the engine. Racing
ECU’s may be used, as long as they were originally supplied by the same
manufacturer as the engine. Ex: Honda motorcycle engines must run ECU’s
that were supplied by Honda on their motorcycle engines.Re-flashing of ECU and factory race ECU’s are allowed. Rev limit
for all 600cc (nothing larger than 600cc) engines is 16,100 rpms. Rev limit
for all 636cc engines is 14, 800 rpms. U6SA specified Rev Limit must remain
intact at all times (no switched or gear specific limiters). If a computer
is hooked up to check the ECU it must be set to U6SA specified rpm’s, no
tolerance. See specifications list for RPM limits.

b)All
cars must have the PA standard connector for the track to check engine rpm
rev limit. These are available from the chassis manufactures and engine
builders, and at the track. All cars must leave intact the rpm wire coming
from the ECU.

and secured in the wiring harness. (the wires must be taped up, not visible,

mechanically forced induction (turbo charging, supercharging)

b)Any
carburetors may be used on any engine, regardless of year of engine.

i)Note:
Switching to carburetors on engines that came with fuel injection usually
increases the rev limiter due to the removal of the injectors as the ECU
cuts fuel to limit rpm’s before it cuts the ignition. A re-flash of the
ECU will be required if using carburetors in order to comply with the rev
limit rule 7. a)

c)If
the engine did not come from the factory with fuel injection, fuel injection
may not be used.
